[PATCH 2/2] pack-objects: Default to zero threads, meaning auto-assign to #cpus

[Brandon Casey <casey@nrlssc.navy.mil>]

Additionally, update some tests for which the multi-threaded result
differs from the single-threaded result and the single-threaded
result is expected.

Two of the tests in t5300-pack-object.sh failed when multiple
threads were used. My fix was to set --threads=1 for all pack-objects
calls. I didn't look into it any further than that. All other tests
passed.
